| 20080209499 | CHANNEL CHANGE LATENCY REDUCTION - A wireless communication system is enhanced to allow for low-latency channel surfing and to enable a user to quickly see the content carried over a selected channel while searching channels for desired content. The techniques for reducing the channel change latency may be implemented in a transmitter, receiver, or in a combination of transmitter and receiver. The wireless communication system is optionally a DVB-H communication system. The transmitter may generate and transmit one or more auxiliary channels, where each auxiliary channel contains reduced resolution content corresponding to one or more channels. The receiver may process the one or more auxiliary channels to present the reduced resolution content while processing the full resolution channel for display. The receiver caches portions of content from one or more non-selected channels and presents the cached content when the channel is selected while concurrently searching and processing the full resolution channel content. | 08-28-2008 |

| 20080320545 | System and method for providing audio-visual programming with alternative content - A system for presenting audio-video programming with alternative content comprises a first input port for receiving a first signal containing at least one audio-video program, the at least one audio-video program having at least one default component associated therewith and a second input port for receiving a selected alternative content stream, the selected alternative content stream selected from a plurality of available alternative content streams. The system further comprises a first output port for transmitting a modified audio-video program to an output device, and at least one controller in communication with the first input port, the second input port and the first output port. The at least one controller is operative to (i) synchronize the at least one audio-video program and the selected alternative content stream to form the modified audio-video program and (ii) transmit the modified audio-video program via the first output port. | 12-25-2008 |
| 20090049501 | DEVICE, METHOD AND SYSTEM OF WIRELESS COMMUNICATION - Some demonstrative embodiments include devices, systems and/or methods of wireless communication. A local wireless video communication network may include, for example, a first group of wireless video source modules capable of transmitting wireless video transmissions; and a second group of wireless video destination modules capable of receiving the wireless video transmissions, wherein the source modules and destination modules are capable of communicating with one another according to a bipartite communication scheme such that each destination module is capable of receiving a wireless video transmission from only a single source module at a given moment, and wherein the number of modules in at least one of the first and second groups is equal to or greater than two. Other embodiments are described and claimed. | 02-19-2009 |
| 20090113513 | System and method for displaying customer-specific audio visual diplays - A system for displaying audio visual presentations based on customer preferences includes an RFID writer, a reader, a display screen and a control system. The RFID writer writes a descriptive code onto an RFID tag, wherein the descriptive code containing customer specific information based on a consumer's purchase. The reader reads the descriptive code from an RFID tag when the tag enters a predetermined proximity of the reader. The control system is operatively coupled to the display screen and the reader and stores a plurality of audio-visual presentations. The control system initiates the display of an audio-visual presentation on the display screen based on the descriptive code, wherein the control system is adapted to play the audio-visual presentation in the order in which the RFID tag is read by the antenna. | 04-30-2009 |

| 20100037283 | Multi-Stream Digital Display Interface - Multiple video streams can be transmitted over a high speed link. A connection with a receiver can be detected by a transmitter. The transmitter can then establish a link with the receiver. Multiple streams of video data can be packed into a transfer unit. The transmitter can then transmit the transfer unit with the multiple stream video data over one or more lanes of the link to the receiver. A high speed communications link between a receiver and a transmitter can transmit data for multiple video streams over a single lane within a data link. The high speed communication link is scalable in bandwidth and video/audio streams transmitted, and backward compatible with other types of video data communication connections. The high speed link may support up to eight video/audio streams simultaneously, thereby enabling full use of data link bandwidth. | 02-11-2010 |
| 20100050224 | DISPLAY APPARATUS AND CONTROL METHOD THEREOF - A display apparatus and a control method thereof are provided. The display apparatus includes: a video processing unit which processes a first video; a display unit which displays the first video; a connecting unit which receives a second video of an image communication from a mobile communication terminal which enables the image communication; and a control unit which controls the video processing unit to process the second video of the image communication to display the second video in the display unit, and controls the mobile communication terminal based on a control command of a user. | 02-25-2010 |
| 20100132007 | ACCELERATING CHANNEL CHANGE TIME WITH EXTERNAL PICTURE PROPERTY MARKINGS - In one embodiment, a method for accelerating channel change time is provided. The method comprises determining when a channel change occurs. A video stream of pictures is then determined. For example, the video stream may be for a channel that is tuned to by a user. Picture discardability information transmitted with the video stream of pictures is determined. For example, the picture discardability information may be transmitted in a data field outside of the video stream. The method then determines which pictures in the video stream are considered nondiscardable pictures and which ones are discardable pictures based on the picture discardability information transmitted with the video stream of pictures. A non-discardable picture stream may then be determined and transmitted to a video processing device. By sending the non-discardable picture stream, a faster channel change time may be provided because it is expected that the non-discardable pictures may be pictures that can be used to display a picture faster than if the regular video stream was transmitted. | 05-27-2010 |
